Functions & Benefits

• Improves water quality by chelating calcium, magnesium, iron, copper, and other metal ions commonly found in hard water.

• Enhances dyeing uniformity by preventing metal-ion interference that can cause shade variation, spots, and uneven dye uptake.

• Improves color fastness, including washing and rubbing fastness, by stabilizing dyes and preventing adverse side reactions.

• Prevents dye hydrolysis and decomposition, particularly in reactive dyeing systems, improving dye utilization efficiency and color brightness.

• Reduces backstaining and redeposition during washing and soaping processes by maintaining dyes and impurities in a stable dispersed state.

• Protects equipment by minimizing scale formation and metal-induced corrosion, extending machinery service life.

• Improves process stability and reproducibility, especially under low liquor ratio, continuous, or high-speed production conditions.
